MACHINERY FOR ROUNDING LEATHER STRINGS.

SPECIFICATION forming part of Letters Patent No. 250,516, dated December6, 1881.

Application filed May 21, 1881. (No model.)

I 0 all whom it may concern Be it known that I, WASHINGTON FOGLE- SONG,a citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented a new and useful Machine forRounding Leather Strings, of which the following is a specification.

My invention relates to a machine having two rollers, one having aseries of grooves, the bottoms of which forming semicircular faces, andthe other having a corresponding series of flanges, which enter saidgrooves with like faces, the said races being equidistant from theiraxes. At the point of intersection these faces are moved together at auniform speed by means of two cog-wheels of equal diameter attached tothe axles of the rollers. The semicircular facrs, where contiguous, forma circular orifice, through which the leather strips are carried byadhesion to the rolls, and thus are formed round strings in anexpeditious manner.

The mechanism is illustrated in the accompanying drawings, in whichFigure I is a fi out elevation of the leather-string machine. Fig. 11 isa transverse section of the rolls through the groove and flange. Fig.III is a rear view of the guide-plate.

A represents a substantial cast-iron frame with two uprights. In centralcavities of the uprights are placed the ordinary form of boxing, whichforms bearings for the axles of the rolls. Screws enter the upright overthe box ing, for the purpose of adjusting the rolls and holding them inproper relation.

On the top of the uprights is attached a thin plate, 112, of steel,which has projections entering the grooves to force the leather stringout of the same. Attached to the bottom is a similar plate, n, whichcovers the flanges and cleans them of any portion of leather which mayadhere to them.

The roll B is cylindrical in form, and has a series of grooves cut inits periphery, with parallel sides, terminating in semicircular bottomsor faces. It is supported in bearings, as before described, and externalto the frame has attached a cog-wheel, O, which gears into another ofequal diameter, which is attached to the axle of the roll B. This rollhas a series of flanges with parallel sides, terminating in semicircularfaces. These flanges enter the grooves of the upper roll, and thus forma circular orifice, through which strips of leather are passed for thepurpose of rounding the same. The rolls are of equal diameter at theirsemicircular faces and rotate in opposite directions. The sizes of theholes formed between the rolls vary slightly in size.

F is a guide fitted closely to the rolls, and is attached to the frame.The position and size of the horizontal holes through the samecorrespond to the position and size of the circular grooves of therolls.

The machine may be driven by power or hand, and when driven by hand theWheel D is attached to the axle of the lower roll, a suitable handlebeing attached to the same.

The operation is thus: The leather is cut in strips of uniform width. Anend being placed in the largest hole of the guide, the rolls are turned,and when the end is far enough through it is entered in the second holeand again in the third hole, and when the strip has thus passed throughthe machine it is uniformly round and smooth.

I do not regard my invention as confined to rolls having a series oforifices, but one or any desirable number which may prove advantagnous.

The machine may be varied in other particulars, the essential featurebeing the semicircular faces of the grooved and flanged rollers.

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, is-

1. The roll B, having a series of grooves terminating in semicircularfaces, with flanges of roll B snugly entering the said grooves, the saidflanges terminating in corresponding faces, thus forming a circularorifice between said faces, substantially as and for the purpose setforth.

2. The rolls B B, constructed substantially as set forth, in combinationwith the frame A, cog-wheels 0, plates at and. n, and guide F,substantially as set forth.
